Has Onslaught been gutted?

Sorry if someone else has posted this question, but I cannot find the answer yet. Onslaught Support was used in my old build for lower level farming for the movespeed etc, but never really in my build as a core part of it. I saw on the patch notes that it says:

Onslaught Support Now grants supported skills a 10% chance on Hitting a Unique Enemy to grant Onslaught for 3 Seconds.

Which I at first thought was a nice buff to it because it's sad to lose those additional speeds when killing the last boss in a map etc. However, if you look at Phantasm on Kill:

Summon Phantasm on Kill Support Now ALSO grants a 10% chance to summon a Phantasm when supported skills, or non-phantasm minions from supported skills, hit a Rare or Unique enemy.

It implies that this change adds something as it says "ALSO". I waited for the gems to be released today but Onslaught Support isn't there and I wondered if anyone had any idea of what will have happened to it?

Thanks in advance for any answers.
